The .22 semi - automatic anshuzt rifle was given the exhibit reference 'DRH/15' item reference no. 18..
The exhibit reference no. and the item number ('DRH/15 -18'), tell us that the rifle (.22 semi-automatic Anshuzt rifle) was seized, found, or recovered by 'DC David Robert Hammersley' (Witham SOCO) and that it was the 15th item in sequence that he took possession of at the scene on the first morning of the police investigation into these five deaths. Other items that he seized, found or that he took possession of before he seized, found, or that he took possession of rifle 'DRH/15 - 18', for example, exhibits 'DRH/1, 2, 3, 4, 5, 6, 7, 8, 9, 10 , 11, 12 13 and 14', were all seized, found or taken possession of at the scene in sequential order, one after the other, up to and inclusive of exhibit reference 'DRH/15 - 18', and beyond, right up in sequence to exhibit reference 'DRH/53' (last exhibit ever attributed as having being seized, found or taken possession of at the scene, or elsewhere, for that matter, for example, at the mortuary during the autopsies performed by the pathologist, Peter Venezis, on 7th and 8th August 1985)..
Of some concern, as uncovered by me in my research into this part of the police investigation into these five deaths (Scenes of Crime reference no. 'SC/688/85' [ 7th August 1985 - 8th September 1985], and from then on 'SC/876/85' [8th September 1985, onward], and the curious fact that during the first part of the investigation ('SC/866/85') the first four exhibits, seized, found or taken possession of by 'DC David Robert Hammersley' at the scene on 7th August 1985 ('DRH/1, 2, 3 and 4' were not exhibit reference items, a .22 bullet case 'DRH/1', a .22 bullet case 'DRH/2', a bullet case 'DRH/3', and a bullet case 'DRH/4', but that rather 'other items of evidential value, which by the start of the second part of the police investigation 'SC/786/85' ( 8th September 1985,, and onward) became referred to as exhibit references, 'DRH/50', 'DRH/51', 'DRH/52' and 'DRH/53', which paved the way for the introduction of ' four .22 bullet cases' , into the case file 'SC/876/85', as though these four bullet cases had been the first exhibits seized, found or that 'DC Hammersley' had taken possession of at the scene on the first morning of the original police investigation (7th August 1985), yet a different set of evidential items (later altered and changed from 'DRH/1' to 'DRH/50', 'DRH/2' to 'DRH/51', ' DRH/3' to 'DRH/52', and 'DRH/4' - 'DRH/ 53' ( Scenes of Criime references 'SC/688/85' and 'SC/786/85')...
In a nutshell, a total of 8 exhibits which at one time or another, were allocated the exhibit references, 'DRH/1', 'DRH/2', 'DRH/3' and 'DRH/4'...
